  1. Akao Y, Yoshida H, Matsumoto K, Matsui T, Hogetu K, Tanaka N, et al. A tumour-associated DEAD-box protein, rck/p54 exhibits RNA unwinding activity toward c-myc RNAs in vitro. Genes Cells. 2003;8:671-6 pubmed
    ..These findings strongly suggest that rck/p54 may play an important role in translation initiation by restructuring mRNAs even in the cell and contribute to carcinogenesis. ..
  2. Akao Y, Seki N, Nakagawa Y, Yi H, Matsumoto K, Ito Y, et al. A highly bioactive lignophenol derivative from bamboo lignin exhibits a potent activity to suppress apoptosis induced by oxidative stress in human neuroblastoma SH-SY5Y cells. Bioorg Med Chem. 2004;12:4791-801 pubmed
    ..These data suggest that lig-8 is a promising neuroprotector, which affects the signaling pathway of neuronal cell death and that it would be of benefit to delay the progress of neurodegenerative diseases. ..
  3. Akao Y, Matsumoto K, Ohguchi K, Nakagawa Y, Yoshida H. Human DEAD-box/RNA unwindase rck/p54 contributes to maintenance of cell growth by affecting cell cycle in cultured cells. Int J Oncol. 2006;29:41-8 pubmed
    ..These data suggest that rck/p54 contributes to cell growth possibly by modulating translation-initiation control of the genes involved in the cell proliferation, which is a newly defined mechanism leading to carcinogenesis. ..
  4. Akao Y, Nakagawa Y, Iio A, Naoe T. Role of microRNA-143 in Fas-mediated apoptosis in human T-cell leukemia Jurkat cells. Leuk Res. 2009;33:1530-8 pubmed publisher
    ..These data suggest that the up-regulation of miR-143 could be related to the apoptosis in part by targeting ERK5, which leads to promotion of Foxo3a/FasL positive feedback loop. ..
  5. Akao Y, Nakagawa Y, Kitade Y, Kinoshita T, Naoe T. Downregulation of microRNAs-143 and -145 in B-cell malignancies. Cancer Sci. 2007;98:1914-20 pubmed
    ..Taken together, these findings suggest that miRs-143 and -145 may be useful as biomarkers that differentiate B-cell malignant cells from normal cells and contribute to carcinogenesis in B-cell malignancies by a newly defined mechanism. ..
  6. Akao Y, Nakagawa Y, Iinuma M, Nozawa Y. Anti-cancer effects of xanthones from pericarps of mangosteen. Int J Mol Sci. 2008;9:355-70 pubmed
    ..These findings could provide a relevant basis for the development of xanthones as an agent for cancer prevention and the combination therapy with anti-cancer drugs. ..
  7. Akao Y, Nakagawa Y. Expression of the DEAD-box/RNA helicase rck/p54 in mouse tissues: implications for heterogeneous protein expression. J Histochem Cytochem. 2006;54:955-60 pubmed
  8. Akao Y, Nakagawa Y, Naoe T. let-7 microRNA functions as a potential growth suppressor in human colon cancer cells. Biol Pharm Bull. 2006;29:903-6 pubmed
    ..These findings suggest the involvement of let-7 miRNA in the growth of colon cancer cells. Thus, miRNAs might provide a basis for novel RNA anti-cancer agents. ..
  9. Akao Y, Banno Y, Nakagawa Y, Hasegawa N, Kim T, Murate T, et al. High expression of sphingosine kinase 1 and S1P receptors in chemotherapy-resistant prostate cancer PC3 cells and their camptothecin-induced up-regulation. Biochem Biophys Res Commun. 2006;342:1284-90 pubmed
    ..These findings strongly suggest that high expression and up-regulation of SPHK1 and S1P receptors protect PC3 cells from the apoptosis induced by CPT. ..
